The Dink Network

Um, can someone explain to me how to use it? When I click on the link for the help.html in the help menu the ReadMe.txt mentions, it brings up some menu for packaging stuff... I tried doing File>Open Map.DAT, then typed powgem into the script thing in the find/replace window, then ticked the delete box on the modify window. It says it found and deleted two sprites, but then if I open WinDinkEdit, or close and open Sprite Replacer then the sprites are still there. Is there a step I'm missing?

EDIT: Nevermind, worked it out, I was forgetting to do File>Save afterwards
